KEY MESSAGES

- A warm-up next week will send temperatures back above normal for late October, with dry conditions.

SHORT TERM /THROUGH SUNDAY NIGHT/

Issued at 201 AM CDT Sat Oct 17 2026

It certainly feels chilly early this morning! Temperatures overnight have fallen into the mid to upper 30s across much of the DVN CWA While light winds are conducive for frost development with these temperatures, dewpoints in the mid 30s may help limit frost through at least part of this morning. Both a Freeze Warning and a Frost Advisory are in effect through 9 AM this morning, with the warning along and north of a Fairfield to Sterling line and the advisory to the south. Following this seasonably cold start to the day, a sunny and pleasant day is in store, with highs in the mid 50s to near 60 degrees and light southwesterly winds.

Yet another night of near-freezing lows is in store tonight, albeit a few degrees warmer as warmer air gradually advects into the area. This should limit widespread frost coverage, though any cooler areas will still be susceptible to at least patchy frost. With high pressure moving to the southeast and southerly winds, yet another sunny day with slightly warmer temperatures in the 60s is expected.

LONG TERM /MONDAY THROUGH FRIDAY/

Issued at 201 AM CDT Sat Oct 17 2026

Following warmer temperatures on Sunday, the week ahead looks pleasant, with above normal temperatures increasing through the week. High pressure will reign through Friday as the center of the high migrates from the central US to over the Great Lakes. Midlevel flow will remain southwesterly, providing WAA that will lead to above normal temperatures through the week. A few shortwaves are expected to move through and bring some cloud cover to the region, though dry low levels will keep us free from any precipitation through much of the week.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 535 AM CDT Sat Oct 17 2026

VFR conditions to prevail through the period. High pressure ridge to slide east into Illinois, with SSW winds remaining under 15kts through the afternoon.
